rarest CHARLES A. UPSON, OF LOCKPORT, NEW YORK, ASSIGNO R TO THE HESS-NCOMPANY,

OF LOCKPORT, NEW YORK, A CORPORATION OF NEW R VIALL AND CEILINGC0N$TRUCTIO1\ Application filed June 18, 1925.

My present invention relates to wall and ceiling construction and moreparticularly to the use for this purpose of the heavy fibre product orpaper known as wall board, and the invention has for its object toprovide an improved form of molding in combination with the wall boardor composition board whereby it is possible to up ply the wall board tothe walls and finish a room with a panelled effect inexpensively andquickly and at the same time obtain a very attractive wall. To these andother ends the invention resides in certain improvements andcombinations of parts all as will be hereinafter more fully described,the novel features being pointed out in the claims at the end of thespecification.

In the drawings:

Figure 1 is a plan view of a portion of a wall panel constructed inaccordance with and illustrating one embodiment of my invention;

Figure 2 is a section on the line 22 of Figure 1 Figure 3 is aperspective view of a portion of the panel as shown in Figure 1;

Figure 4 is a sectional view through the molding, wall and strip, thatis illustrative of the manner of painting under the molding and Figure 5is a view similar to Figure 4 showing the position of the paint coatafter a shrinkage has occurred in the wall.

Similar reference numerals throughout the several views indicate thesame parts.

In the modern lining or construction of the walls and ceilings of roomsin build ings, the use of wall board has greatly increased because ofits cheapness, convenience, its pleasing appearance and many otherattributes. Such wall board consists of heavy plies of fibre ofconsiderable thick ness, usually laminated in panels to be easilyhandled, and it is applied to the studding to'produce a flat surface. Itis desirable to break this up into panels to make a more pleasingeffect. It is also desirable to cover the scams or joints betweenabutting sections of the board with strips that may be worked in to formparts of the panels. WVith the present invention I provide a neat andconvenient mode of applying these panel strips through the use of SerialNo. 37,950.

specially formed moldings that are easy to produce and easy to apply andwhich, in addition, atford facilities for preventing the shrinkage ofthe panels after painting from showing the paint line at the junctionwith the moldings.

Referring to the drawings 1 and 1 indicate sheets of wall board forminga wall and abutting each other at 2. Over the crack formed by theseabutting edges I superpose a strip 3 of the same material and of greateror less thickness according to the effect that is desired in the panel.This strip is secured in place by wooden moldings i which are nailed tothe boards 11 as indicated at 5. The moldings may be of any desiredornamental design but mechani cally they have cut on their under sidesand in the thicker portions thereof rabbets 6 of a depth equal to thethickness of the strip 3. The shoulder thus formed overlies the edge ofthe strip and holds it in place. Of course, in working out the panelscheme, some of the strips 3 will be over the scams 2 and others notbeing applied directly to one of the boards at a properly spaced point.

The opposite and usually thinner edges of the moldings are also providedon their under sides with shallow rabbets 7. These are of such littledepth that they are not noticeable against the surfaces of the boards 1and 1 and yet they give sufficient clearness to permit a paint brush tobe inserted under the edge of the molding and to cover the board up tothe concealed inner wall of the rabbet as indicated at 8 in Figure 4.Thus, should any of the connected elements shrink or settle so that theboard pulls away from the molding an unpainted line at the edge of themolding is not revealed being concealed within the rabbet as shown at 9in Figure 5.

This mode of construction is useful in other instances besidespanelling. For instance, the strip 3 may constitute a base board placedat the floor line or be arranged at the angles of ceiling or side walls.The strips can be arranged in many artistic effects and the stripshaving no knots or bad spots are quickly and easily nailed in place withvery little or no waste. In fact, waste ends or cuttings of the wallboard as manufactured can be utilized in the making of and a shallowrabbet in the under. side of the strips. its opposite edge ofisettingthe latter from i I claim as my invention: the surface of the board towhich it is ap- In a wall construction, the combination plied andpermitting the bristles of a paint with a Wall board and a panellingstrip brush applied to the Wall board to engage superposed thereon, of amoulding secured the same beyond the edge of the moulding. to the wallboard having a shoulder on one side engaging the strip to hold it inplace CHARLES A.
